Summary
Serum estradiol and free testosterone levels are linked to bone mineral density in elderly men. Testosterone may convert to estradiol, influencing bone health.
Area of Science:
- Endocrinology
- Gerontology
- Bone Metabolism
Context:
- Bone mineral density (BMD) is a critical indicator of skeletal health in aging populations.
- Hormonal changes, particularly in androgens and estrogens, play a significant role in bone maintenance in men.
Purpose:
- To investigate the association between serum estradiol level (ESL) and serum testosterone level (TSL) with bone mineral density (BMD) in men aged 60 and over.
Summary:
- A cross-sectional study of 127 healthy elderly men found significant positive correlations between ESL and BMD at the lumbar spine and femoral neck.
- While TSL showed no correlation with BMD, calculated free testosterone level (FTL) was positively associated with BMD at both sites.
- These associations remained significant after adjusting for body mass index and age.
Impact:
- Serum estradiol levels and free testosterone levels are independently associated with bone mineral density in elderly men.
- Findings suggest that peripheral conversion of testosterone to estradiol may be a contributing factor to bone health in aging males.
- Highlights the importance of monitoring sex hormone levels in older men for assessing osteoporosis risk.

01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:17Hormones and Bone Tissue
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:28Menopause
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...
01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are not...
01:09Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
